The utility model can complete verification at limited highway toll station and possesses convenience, fastness, high efficiency and simple and practical structure.
Description
Technical field
The utility model relates to a kind of calibrating installation, the calibrating installation of particularly a kind of highway weight metering charging device or equipment.
Background technology
Before the utility model is made, comprise at highway that at present employing weight metering chargings such as high-grade highway, highway are a trend.This just need be provided with weight metering charging device or equipment in toll station, so that vehicular traffic is carried out weight metering charging.So, the meter of weight metering charging device or equipment heavy accurately or accuracy directly affect the carrying out of charge.At present, original mode efficient of piling up counterweight is low, and workload is big, and on-the-spotly needs bigger space lift by crane the prestowage piece one by one with loop wheel machine; Reaction frame then can't be installed and used at the toll station scene especially, and it needs bigger space.Therefore, in toll station gravity measure device or equipment are counted heavily calibrating and become very urgent and important, otherwise will have a strong impact on the regular fee work at charge station road junction.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned defective, designs the heavy instrument calibrating of a kind of weight metering charging axle (wheel) car.
The technical solution of the utility model is: highway weight metering charging axle load meter calibrating car, comprise load-carrying members and prestowage piece composition static pressure source, its major technique is characterised in that the static pressure source is arranged on the load carrier, the static pressure device is made of hydraulic means, master cylinder, force transducer and master cylinder point-blank, force transducer output connects weight and becomes and send and Displaying Meter.
Advantage of the present utility model and effect are and can examine and determine weight metering charging device or equipment in the limited space of toll station, in verification process, can carry out coarse adjustment and fine setting, the precision height, realize computerized data acquisition and focus on, have easily and fast and characteristics of high efficiency, can carry out full scale meter remeasurement.And the utility model is simple in structure, practical.

Embodiment
As shown in Figure 1 and Figure 2, load-carrying members 1 and the prestowage piece 2 that is placed on it constitute the static pressure source, load-carrying members 1 and prestowage piece 2 are placed on the load carrier, and load carrier can be semitrailer (containing single shaft, twin shaft and multiaxis), full trailor, self-propelled bicycle etc.; Hydraulic means 3, master cylinder 4 constitute the static pressure generation device, and wherein hydraulic means 3 is made of electric hydraulic station 9, manual pressure pump 10 and pressure fine setting device 11; High-precision force sensor 5 is placed or is installed in and leads on the power support 6, lead power support 6 by right lift cylinder 7, wirerope 14 be suspended on master cylinder 4 under, right lift cylinder 7 is the longeron of load-carrying members 1 15 times, master cylinder 4 also is installed in the longeron 15 times of load-carrying members 1, and left lift cylinder 8 also is installed in the longeron 15 times of load-carrying members 1.
As shown in Figure 3, high-precision force sensor 5 connects the weight change and send and Displaying Meter 12, and weight becomes to be sent and Displaying Meter 12 connection computing machines 13, and computing machine 13 is control system and data computer; The weight change send and the output of Displaying Meter 12 or computing machine 13 connects hydraulic means 3.
During use, as Fig. 1, Fig. 2, shown in Figure 3, with the load carrier of carrying load-carrying members 1 and prestowage piece 2 is that trailer is parked in axle load meter or wheel weighing instrument top, right lift cylinder 7 will be led power support 6 and be put down, be placed on the weighing platform of axle load meter, with wirerope 14 with lead after power support 6 separates, left lift cylinder 8 puts down master cylinder 4, makes it and places or be fixed on the high-precision force sensor 5 of leading on the power frame 6 and keep same straight line; Computing machine 13 or weight become give and Displaying Meter 12 on test point is set, and start electric hydraulic station 9 automatically, what electric hydraulic station 9 adopted is the electrical servo hydraulic power unit, auto stop when reaching set pressure; The manual pressure pump of perhaps enabling on the hydraulic means 3 10 reaches desired pressure, and there are deviation in expression value in accordance with rites and set pressure, can adjust pressure to setting value by the fine setting of the pressure on the primer fluid pressure device 3 device 11; The closed loop that can use a computer and manual two kinds of control modes of open loop; After calibrating is finished, computing machine 13 exportable test curves, simultaneously left lift cylinder 8 is mentioned master cylinder 4, and right lift cylinder 7 will be led power support 6 and be mentioned, and tested location survey examination vehicle can leave the track.
The calibrating scope can comprise the full scale of axle load meter, also can examine and determine axle load meter at any measurement point.
Because load carrier such as semitrailer (containing single shaft, twin shaft and multiaxis), full trailor, self-propelled bicycle need not fix on the ground, and can move voluntarily, and load-carrying members 1 and prestowage piece 2 are all disposed thereon, therefore fast, safely and efficiently.
Static pressure generation device, the force transducer 5 that master cylinder 4, hydraulic means 3 constituted, lead longeron 15 belows that power support 6, left lift cylinder 8, right lift cylinder 7 etc. are arranged on load-carrying members 1, what have is directly installed on it, easy to use, transportation.
The weight change send and Displaying Meter 12 also can directly be transferred to hydraulic means 3 with data.
